If you are a new gardener or living in an area with fluctuating climates, growing plants indoors is the perfect way to provide your household with fresh produce throughout the year. When temperatures drop during winter months, and outdoor gardening becomes difficult, heating up a greenhouse can be one of many ways to keep vegetables and fruits from going bad on their vines.
One effective way of heating your greenhouse during colder temperatures is by using a solar heat system. This can be very efficient because the size and temperature inside will determine how much energy you’ll need to use for other methods, like natural gas or oil-fired systems in places where it can drop below zero degrees outside.
Can a Greenhouse be Heated with Solar Panels?
Space heaters are the most popular and reliable way to keep your greenhouse warm overnight, but solar panels can also be used as an alternative. During the daytime, when you don’t need a space heater, use solar energy from PV panel-powered fans that will circulate warmer air into your home’s greenhouses.
The idea of heating your greenhouse with a solar panel is not unheard of. You would need PV solar panels, a set of batteries, an inverter, and a heater in order to make it work properly. Sounds complicated? Well, here’s the good news: there are specialists out there who can help you with that!
But is it practical? Yes, that’s an important question that depends on certain factors like the size of your greenhouse, the heat requirement based on ambient temperature, and how much money you’re willing to spend.
